COMBINED PENCIL HOLDER AND SHARPENER.

To all .whom it may concern:

Be it known that-I, CONRAD H. HAASE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful- Improvements in Combined Pencil Holders and Sharpeners, of which the-following is a specification.

This invention relates to pencil sharpeners, and has for its object to provide an improved device of this kind which may also be placed over the point of the pencil to protect it when notinuse; and to this end the invention consists in a novel arran enient and combination of parts to be herea ter described and claimed.

In the accompanying drawing, Figure 1 is a longitudinal section of the device assembled. Fig.2 is an elevation of the case oris an elevation of the sleeve whereby the pencil tube which receives the pencil.

is advanced and retracted. Fig.4 is a crosssection on the line 12-of Fig. 3. Fig. '5 is' an elevation of the sharpener. Fig. '6 is a cross-section on the line ,34 of Fig. 5. Fig. 7 is an elevation of the complete holder and sharpener. Fig. 8 is a cross-section on the line 56 of Fig. 1. Fig. 9 is an elevation of a modified form of sharpener.

Referring specifically to the drawing, A

. is a case or tube of suitable length into which the pencil is'placed. The tube is angular in also angular,in cross section so that the;

cross section and receives a pencil which is pencil cannot "rotate therein but is free to slide up andfdown in ,the tube. On one end of the .tube .A is mounted a sleeve B which projects a short distance from the tube and has in said projecting portion interior threads i which are stamped into the body of the sleeve. Adjacentwthe end oi the tube A is a circularflange Z over which fitsa rim e on the inner end of the sleeve B whereby said sleeve isrsecured to the tube against lengthwise separation but 1s free .to rotate thereon.

Thesharpener is-a tube G which on the sleeve B and projects a suitable distance beyond the outer end thereof, said projecting end of the sharpener being cone-sha ed' and havin oneor more .slits g'. The s have one o their-edges bent inwardly to act as a cutter for trimmingthe wooden casin 'of the pencil to'a point. The extreme en of the. sharpener has crossed slits hand a,"

respectively, so that when the point of the pencil reaches it and the pencil is continued to be fed forwardly, said end will spread apart to expose the point of the pencil ready for use. The edges of the slits h and it cut Specification of Iietter' latent. Patented Nov, 34) 19021 Application fi led Hay QB, i968. Serial Nb. 434,686.

or scrape the exposed'end of the lead and point it. The butt-end of the tube C has longitudinal slots 0 which receive tongues m struck up fromthe sleeve B, so that said tube and sleeve Will rotate together when the tube is rotated. The tube however can be slipped off the sleeve lengthwise in order to remove the stump of the pencil from the tube A. v

On the butt-end of the tube A may be placed a rubber cap I) to serve as an eraser, and the outer surface of thetube may be suitably grnamented, or used to display an advertisement.

In use, the pencil is inserted into the tube A at the rear end thereof by removal of the cap. D and pushed forwardly until the threads f will bite into the wooden casing of the pencil when the sleeve ,B is rotated by the tube C. 'The threads fl'indent the wood of the pencil and form threads therein, thereby operating to feed the pencil forwardly or to retract the same when the sleeve is When the penal is not in use the point may be drawn backiinto the tube by rotating the same in a direction to retract the pencil.

Thedevice herein described is simple in construction and can be cheaply produced. It can be applied-to anyjordinary pencll or marking crayo and itis easy to operate to sharpen the encil or to withdraw it into -thetube G. T e pencil can be used up to a very short stump which is readily removed uponslipping the tube C-oif'the sleeve B.

In the drawing I have shown three cutters g which if put in a line would cover substantially the entire length ofthe cone-shaped portion} of the tube C, but a similar result .lnay; be had by more or less cutters, of course in such cases the' cutte vbei'nglonger or shorter according to their number.

In Fig. 9 is shown a modified form of sharpener. In this case the sleeve B is dispensed with and the sharpeningtube C is applied directly to the case or tube A in the same manner as the sleeve B. The threads f for advancing or retracting the pencil are on the sharpening-tube. This form of sharpener operates in the same manner as the one first described: viz., by turning either the tube C or the tube A. In the modified form of sharpener the stump of the pencil removed by turning the tube A or C rearwardly until the stump is released from the threads after which it can be easily shaken out of the butt-end of the tube.

The holder may be used without the sharpener for the purpose of giving the pencil a uniform length throughout its whole use, and to be able to use it up to a very short stump, and to be able by a return movement of the sleeve B to protect the point of the pencil. Of course, in this case the pencil will have to be sharpened either with a knife or by other means. The sharpener may also be used separately without the holder.

It is to be understood that various changes in'minor details may be made, without departing from the spirit of, or sacrificing any of the advantages of the invention.

I'claim:

l. A pencil-sharpener comprising a tubular casing receiving the pencil, a sleeve rotataloly mounted on the casing and projecting from one end thereof, the projecting end of the sleeve having interior screw-threads engageable with the pencil, and pencilsharpening means carried by the sleeve.

2. A pencil-sharpener comprising a tubular casing receiving the pencil, a rotary sharpener carried by the casing and having a conical end projecting therefrom to inclose the end of the pencil, interiorprojecting cutters on said conical end, a sleeve rotatable on the casing, and having threads engaging the pencil for projecting the point of the pencil from the sharpener and for retracting the same thereinto, and means for preventing the sleeve from traveling.

3. A pencil-sharpener comprising a tubular casing receiving the pencil, a sleeve rotatably mounted on the casing and projecting from one end thereof, the projecting end of the sleeve having interior screwthreads engageable with the pencil, and a pencil-sharpener comprising a tube mounted on the sleeve to rotate therewith, and having a cone-shaped end to receive the pencil point and provided with inwardly projecting cutters.

4:. A pencil-sharpener comprising a tubular casing receiving the pencil, a sleeve rotatably mounted on the casing and projecting from one end thereof, the projecting end of the sleeve having interior screw-threads engageable with the pencil, tongues projecting from the sleeve, and a pencil sharpener comprising a tube mounted on the sleeve and having a slit to receive the tongues, said tube having a cone-shaped end to receive the pencil and provided with inwardly projecting cutters.

In testimony whereof I affix my signature, in presence of two witnesses.
